En este trabajo se plantea, más allá de examinar las tesis principales del "revisionismo", la propia naturaleza del conocimiento histórico. ¿Son válidas todas las interpretaciones de un hecho histórico? ¿Se trata en tales casos de "otra lectura", de una "versión alternativa", es decir, de otra apreciación de los datos disponibles? ¿Cómo saber cuando hay mala interpretación deliberada o falsificación de la evidencia? ¿Puede detectarse si la argumentación tendenciosa es deshonesta? El "revisionismo histórico" se ha definido a sí mismo como una corriente historiográfica que ofrece otra versión de Hitler y su régimen. Cerca de una veintena de autores, desde los años cuarenta del siglo XX, se adscriben en esta tendencia, algunos de los cuales han desplegado una sostenida actividad y han logrado una llamativa repercusión en los medios de difusión. Este es el caso de David Irving. Autor de más de treinta libros, artículos, conferencias y discursos dedicados al III Reich, ha pasado largos años de su vida rastreando y estudiando archivos alemanes. Pero muy lejos de constituir un nuevo enfoque historiográfico del nazismo, el "revisionismo" de David Irving está imbuido de política e ideología y sus métodos de trabajo incluyen la adulteración y la distorsión intencional de la historia.

An integrated instrument package for measuring and understanding the surface radiation budget of sea ice is presented, along with results from its first deployment. The setup simultaneously measures broadband fluxes of upwelling and downwelling terrestrial and solar radiation (four components separately), spectral fluxes of incident and reflected solar radiation, and supporting data such as air temperature and humidity, surface temperature, and location (GPS), in addition to photographing the sky and observed surface during each measurement. The instruments are mounted on a small sled, allowing measurements of the radiation budget to be made at many locations in the study area to see the effect of small-scale surface processes on the large-scale radiation budget. Such observations have many applications, from calibration and validation of remote sensing products to improving our understanding of surface processes that affect atmosphere-snow-ice interactions and drive feedbacks, ultimately leading to the potential to improve climate modelling of ice-covered regions of the ocean. The photographs, spectral data, and other observations allow for improved analysis of the broadband data. An example of this is shown by using the observations made during a partly cloudy day, which show erratic variations due to passing clouds, and creating a careful estimate of what the radiation budget along the observed line would have been under uniform sky conditions, clear or overcast. Other data from the setup's first deployment, in June 2011 on fast ice near Point Barrow, Alaska, are also shown; these illustrate the rapid changes of the radiation budget during a cold period that led to refreezing and new snow well into the melt season.

El presente trabajo consiste en notas de una investigación en curso. Las mismas dan cuenta del dispositivo de escritura de Washington Cucurto en relación con la pija de oro del negro que se implanta el narrador/personaje Tyson Grande/ Washington Cucurto/Norberto Vega en Las aventuras del Señor Maíz (2005). Nos interesa pensar que esa prótesis quirúrgica y corporal exhibe fuerzas (en un sentido deleuziano) que rigen toda la producción de Cucurto/Vega: la social, la económica, la sexual y la cultural latinoamericana. La pija de oro es, entonces, una condensación poética que exhibe la máquina de escritura como una bestia melancólica en cuyo cuerpo se desequilibran fuerzas en disputa por la literatura

Benthic oxygen fluxes calculated from in situ microelectrode profiles arc compared with benthic flux chamber O2 uptake measurements on a transect of eight stations across the continental shelf and three stations on the slope of Washington State. Station depths ranged from 40 to 630 m and bottom-water oxygen concentrations were 127-38 µM. The fluxes measured by the two methods were similar on the slope, but on the shelf, the chamber flux exceeded the microelectrode flux by as much as a factor of 3-4. We attribute this difference to pore-water irrigation, a process which apparently accounts for the oxidation of a significant amount of organic C in the continental shelf sediments. Combining our diffusive flux data with other data demonstrates clearly that the bottomwater oxygen concentration must play some significant role in determining the sedimentary oxygen consumption rate. Numerical simulation of the microelectrode 0, profiles suggests that roughly half the diffusive 0, flux must be consumed within - 1 mm of the sediment surface. If this conclusion is correct, then the magnitude of the diffusive flux depends both on the bottom-water oxygen concentration and on the supply rate of labile C to the sediment surf'ace.
